[0002] With the development of economy, the problem of air pollution is becoming more and more serious. According to relevant research reports, people spend 90% of their time indoors, and the indoor pollution level can even reach more than 100 times that of outdoor pollution. It can be seen that the environmental pollution caused by inhalable particulate matter and harmful substances is very serious. When people feel the weather is hot indoors, they will use fans or air conditioners, and the most used ones are fans. Most of the existing fans only have the function of blowing air, or some other auxiliary functions, such as aromatherapy, etc. What kind of gas is inhaled at the back of the existing fan is what kind of gas is blown out, and the inhaled air cannot be further processed. It is just a device for air circulation. According to the severity of the indoor pollution mentioned above, people need a fan with air purification function, especially a fan that can decompose and remove harmful gases such as formaldehyde, xylene, toluene, TVOC, etc., and when removing harmful substances, it has the effect of environmental protection and energy saving.

Photocatalyst products can release negative ions while purifying the air, that is, the number of negative ions is increased while decomposing toxic and harmful gases, so that the air quality is better, allowing people to enjoy the freshness of nature while having safe and clean air. Photocatalyst is a photocatalyst. In photocatalysis, the photocatalyst only provides a place for reaction, and it itself does not change before and after the reaction.

[0020] Cold catalyst is also called low temperature catalyst or natural catalyst. When the temperature is above 5℃ and the humidity is above 40%, the effect of catalytic decomposition of harmful gases such as formaldehyde can reach an ideal state (the principle is catalytic oxidation). At room temperature, it can decompose various harmful gases into harmless and odorless substances, transforming from simple physical adsorption to chemical adsorption, decomposing while adsorbing, and removing harmful gases such as formaldehyde, xylene, toluene, TVOC, etc. In the process of catalytic reaction, cold catalyst does not directly participate in the reaction. After the reaction, cold catalyst does not change or lose, and can play a role for a long time.
